DUST-GUARD.

'SPECIFICATION forming part of Letters Patent N o. 685,382, dated October 29, 1901.

Application tiled December 1, 1900. SerialNo. 38,288. (No model.)

.T0 all whom, it may concern,.-

Be it known that I, SINOLAIR J. JoHNsoN, a citizen of the United States, residing in Nutley, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dust-Guards, of which the following is a specification'.

This invention relates to improvements in dust-guards for journal-boxes, it being` particularly adapted for use'in connection with railway-cars and the like, and has for its ,ob-I ject the provision of such adevice which shall be efficient in keeping the dust from the bearing and in which portions of the guard maybe readily renewed.

In the drawings accompanyingl this speciication, Figure 1 is a side elevation of a journal-box with a dust-guard made according tothe presentinvention, the portion of the box surrounding the guard and the guard itself being in section. Fig2 is a vertical section of the guard on the line a a of Fig. 3. Fig. 3 is an enlarged side elevation of theV guard, parts being broken away. Fig. l isan enlarged end elevation of a portion of the journal-box. Fig. 5 is the top plan view thereof. Fig. 6 is a partial elevation of another form of the invention, one of the frame-plates being removed. Fig. 7 is a vertical section on a line b b of Fig. 6. Fig. 8 is a det-ail showing the means for fastening a facing-'strip to the frame.

Similar characters designate like parts in the different figures of the drawings.l

One form of my invention is shown in con# nection with a journal-box, (designated in a general way by 13,) in which is mounted a journal J. This box may be of any desired form, but is preferably one which is provided at or nearits inner end with a chamber B' to receive the dust-guard, (designated as a whole by Di) The'openingat the top'of the chamber B may be closed by a removable cover B".

The dust-guard comprises a frame, here I shown as made up of metal side Vplates 11 11, and intermediate filling pieces or blocks 12, preferably of wood, closing three sides of the frame and having an opening 12 at the remaining side. Instead of being made in a plurality of pieces the piece 12 may be formed or molded of any desired material inppone piece. Rivets 13, passed through'the 4plates and blocks, fasten the parts together.

which will conformitself to the journal, it being shown herein as a brous substancefelt, for example. This'strip substantially -lls the width of the channel and projects morev or less within the edge of the opening 14. Within the frame, in proximity to the opening 12', occupying substantially the full width and extending a portion of the distance between the blocks 12', which are shown as `extending up beyond the journal-opening at this point, is a rigid wear-resisting supporting member 16. In Figs. 2 and 3 this block is shown as riveted in place between the side plates, similarly to blocks 12 but it may be otherwise supported, as will be later explained. The member 16 may consist of a block 16', provided with a shoe 1'7, of steel or other desirable wear-resisting material, upon its inner surface, curved to fit the journal. The flexible guard-strip at the ends of the channel passes up between the member 16 and the blocks 12, producing with the former a practically continuous surface embracing the journal.

To secure the guardfstrip in Idane, it is preferably connected to the member 16 and for this purpose may be provided with a ilexible backing or band 18, to which it is secured. Thisex'tends beyond the guard-strip at each end and may be attached' to hooks or catches 19 upon the outer side or top ot' the member 16, which catches preferably have a spring action and exert their force upward.

To the edge of the frame on the sides and across one face, near the top, is preferably attached a facing-strip of fabric 20, which is doubled to produce a piped or tubular edge 2l, which projects a substantially uniform distance from one face of the frame. This fabric may be tacked in place with an outer securing-strip 22, of thin sheet metal.

In the use ot' the dust-guard it is introduced IOO in place when the journal and its box are assembled, it being placed in its chamber and the journal passed through the openings 1l. The member 16 then rests upon the top of the journal. Its shoe, if one be employed, contacting therewith supports the guard and closes a portion of the opening, while the strip 15 is drawn tightly about the remaining portion against the ends of the member by the circumferential tension produced in it by the spring-catches and completes the closure, preventing dust from entering about the axle. As the guard becomes worn this tension in the spring-supports takes up the stripv and maintainsthe contact. If material were used which wore slowly, the strip might be fastened to rigid instead of spring catches. Vhen the fiexible guard-stri p is worn through, or nearly so, it may be withdrawn by the band attached to it and a new one drawn into the channel without removing the guard-frame from its chamber by attaching its band to that of the one removed or by a wire or the like passed through the channel.

The frame is of such thickness relative to the containing-chamber that when it is in place the tubular edge 21 is pressed against one side of the chamber, while the opposite face of the guard rest-s against the other. The compression of this edge renders this facing-strip capable of adjusting itself to the inequalities of the surface and completes the closure of the journal-box.

In Figs. 6 and 7 a construction is shown whereby the member 16 may be removed from the frame for renewal or to more readily introduce the guard-strip. rlhis may be effected in various ways, two of which are shown. In one, movable pieces, shown as fiat springs 23, are mounted in grooves on each side of the member and carry projections 24, engaging openings in the side plates ll. In the other, similar springs 25 are attached to the end of the member and are provided with projections 26, adapted to enter openings in angle-bars 27, secured to the side plates. In either case the pressing of the springs inward releases the member and permits its withdrawal.

Either of the above devices may be used alone to secure the member, or, if desired, both may be employed.

Although the strip I5 is shown as but partially encircling the journal, it is evident that it might, if desired, be carried entirely about it under the supporting member or otherwise.
